Rio faces new ASIC claims over Riversdale

A Rio Tinto spokesman says the mining giant will "vigorously" contest the latest allegations regarding a writedown of its coking coal assets in Mozambique. The Australian Securities & Investments Commission has alleged that a delay in writing down the value of the assets constituted misleading and deceptive conduct. Rio Tinto, former CEO Tom Albanese and ex-CFO Guy Elliott were already facing allegations that they had not informed shareholders of a significant downgrade in the resource estimate for the Mozambique assets.
